NYC Housing Unit Change by City Council District Since 2010

Net change in housing units for New York City Council Districts is tracked from 2010 onward, derived from Department of Buildings-approved construction and demolition jobs. The NYC Department of City Planning aggregates this data, with the current version reflecting updates through the fourth quarter of 2025. It includes columns for units completed in specific years (e.g., comp2010 to comp2024), filed, permitted, approved, and withdrawn.

Use Cases

• Analyze temporal trends in housing completions by comparing annual completion columns like comp2015, comp2020, and comp2024 across councildst.
• Model the pipeline of housing development by examining the sequence from filed, permitted, approved to completed statuses for each district.
• Assess net housing unit change by calculating the sum of new units from completion columns and subtracting units from demolitions or withdrawals.
• Perform spatial analysis of development density by joining the_geom geometry data with completion counts for different council districts.
• Identify districts with stalled projects by cross-referencing high counts in filed or permitted columns with low counts in recent completion years.

Strengths

• Data covers a 15-year time series from 2010 to 2024, as indicated by completion year columns.
• Includes multiple development statuses (filed, permitted, approved, completed, withdrawn) for tracking project lifecycle.
• Geospatial data (the_geom, Shape_Area, Shape_Length) enables mapping and spatial analysis by City Council District.

Limitations

• Sample data is unavailable, preventing assessment of data distribution, null values, or potential class imbalance.
• The total row count and geographic granularity below the council district level are unknown.
• Relies on administrative records (DOB filings) which may have reporting lags or inaccuracies not reflected in the data.
